COMBINATION OF COOKING-STOVE AND AIR-HEATING FURNACE.

Specification of Letters Patent No. 31,144, dated January 22, 1861.

To all whom if may concern.-

Be it known that I, P. J. ACKERMAN, of Paterson, in the county of Passaic and State of New Jersey, have invented a new and Improved Cook Stove and Air- Heating F urnace; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure l is a vertical section of my invention taken in the line 00, m, Fig. 2. Fig. 2 a

vertical section of the same, taken in the line y, 3 Fig. 1. Fig. 3 a vertical section of the same, taken in the line a, a, Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

' The object of this invention is to obtain a combined cook stove and air-heating furnace by a very simple and economical arrangement of parts which renders the cook stove more desirable than the ordinary ones while all the advantages of an air-heater are obtained.

The invention consists in placing the fire pot of the stove within the ovens; or, having the former in direct communication with the latter and having the ovens communicate with hot air pipes, all being arranged substantially as hereinafter described whereby the desired end is attained.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents a rectangular metal case within which afire pot B, is placed and a, a, are vertical partitions and Z), a-horizontal partition within the case. These partitions form two ovens C, C, and a, passage D, by which they communicate with each other, see Fig. 1.

vided with holes 9, to receive cooking utensils and said plate forms the bottom of a rectangular chamber E, within the case A.

F, is a flue which passes direct from the space between the plates 6, 7, above the fianch 0, up through the chamber E, at its a hot air chamber H, which communicates with the ovens C, C,by means of dampers 2', z. The chamber H, also communicates with the chamber E, by an opening 7'. An ordinary pipe communicates with the chamber H, to convey the heated air to any part of the building. 7

From the above description it will be seen that the fire pot B heats the ovens C, C,

as it is placed within the passage D, which forms a communication between them, and is not exposed to the external air so that no heat is lost by direct radiation. The warm air passes through the ovens C, C, and thence into the chamber H, the dampers z, i, being open, and is conveyed to any desired place by the pipe or pipes which communicate with chamber H. When the ovens are used for cooking purposes the dampers 2', i, are closed. The heat from the chamber E also passes through the opening j, into chamber H. The ovens C, C, and chamber E are provided with doors is. By this arrangement it will be seen that all steam that escapes from the articles in process of cooking passes along with the hot air, none will pass into the apartment unless the door of chamber E be left open, and it will also be seen that the person or operator engaged in cooking will not suffer from the heat of the stove or fire pot as the latter is fully inclosed.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

The combination and arrangement of the ovens C, C, fire pot B, and chambers E, H, as and for the purpose herein set forth.

P. J. ACKERMAN.
